From 5a3e8cde101209edb962ed42091db257f9f5ce5c Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 21 Mar 2018 14:01:52 +0100 Subject: mtd: rawnand: sh_flctl: fix the probe function error path An error after nand_scan_tail() should trigger a nand_cleanup(). The helper mtd_device_parse_register() returns an error code that should be checked and nand_cleanup() called accordingly.
